I am reading this as OP looking at password breach databases (which are, by definition, public and plaintext already), not OP running a service with password registration themselves.
However, I am concerned at how the OP got the string in the first place, that he compared to HaveIBeenPwned? Is he storing his user's passwords in plain text in his back end database, and decided to run them all against the service?? That in and of itself is a security red flag.
